Hitachi, Ltd. announced on June 29 that it will commercialize technology using smartphones and “wearable devices” that you put on and use to revitalize company organizations by measuring their employees’ feeling of happiness based on their active states. The firm will establish a new company, “Happiness Planet” (in Tokyo) on July 20.

To develop the special application, the firm measured the users’ body tremors with the acceleration sensor on smartphones and other devices, and at the same time conducted surveys on their state of mind at each hour of the day to determine the correlation between their physical motion and happiness.

Based on the measurement results of individual employees, the degree of lively activity of the entire workplace is quantified as “happiness levels,” which can be compared between workplaces. AI helps employees communicate with coworkers by, for example, calling on them on the screen to have casual conversations with each other.
